Mutated jadinko males are mutant forms of the jadinko males that reside within Jadinko Lair. Normally responsible for fertilising the Jadinko Queen's eggs, mutant males would attack any of their non-mutated cousins given the chance. They require 91 Slayer to kill. These monsters, along with the level 86 mutated jadinko guards, are the only creatures to drop the whip vine. The males have a higher drop rate, though.

Like all mutated jadinkos, they are a good source of blue charms, noted logs, and medium to high level herbs. They are usually a fast kill and perhaps the fastest source of blue charms.

Each mutated jadinko male kill gives the player 10 favour points with the jadinkos. Each jadinko killed while wearing the Mask of Vines (or associated helm) will increase its kill-counter.

Although they require 91 Slayer to damage, mutated jadinko males are not overly strong. Their damage output is low and they commonly drop food. Additionally, points received from killing them can be traded in for food. They drop mainly noted and stackable items and there is a bank deposit box right up the vine next to the queen. Most players able to damage mutated jadinko males will have high enough combat stats that they can heal solely using the food drops. Soul Split or Rejuvenate/Guthix's Blessing/Ice Asylum/Enhanced excalibur (they all share the same cooldown) can be used to heal if the food drops alone are insufficient.

The seedicide is also very useful as they frequently drop seeds. This can yield around 40,000 to 50,000 Farming experience per hour, depending on the kill speed. They are also great blue charm and elite clue scroll droppers.

Their weakness appears to defy the combat triangle - they attack primarily with melee, but are weak to stab attacks. This results in the monster being ranged-based because of the weakness, but they do not have any ranged attacks. It is unknown whether or not this is intentional.

For a long time after the Evolution of Combat, mutated jadinko males attacked with magic, although before that they used melee attack regardless of armours. With a hidden update they now use their old attack styles, melee only unless the player uses protection prayers, in which case they use magic.
